FIELD OF THE INVENTION

The invention relates to stable, multi-dose liquid compositions containing proteins, in particular, but not exclusively stable antibodies, and to the use of said compositions in therapy, in particular for the subcutaneous delivery of said stable protein.

BACKGROUND OF THE INVENTION

Immunoglobulins, monoclonal antibodies (mAbs) and humanized antibodies have been in development as pharmaceutical products for a number of years. There is a clear incentive for developing multi-dose formulations of mAbs due to the potential for repeated dosage which results in higher convenience for the patient. However, multi-dose formulations must contain antimicrobial agents to protect them from microbial contamination during multiple dosage withdrawal. Multi-dose formulations containing preservatives offer several advantages over single dose containers. For example, product wastage is minimized because different sized doses may be obtained from the same container. Additionally, doses may be obtained from the same container over a period of time without the concern for microbial growth. Furthermore, packaging is minimized because multiple doses are supplied in a single vial.

There is therefore a great need for a stable, multi-dose liquid pharmaceutical antibody composition.

However, the effect of the preservative on protein stability is a major concern. Anti-microbial preservatives are known to interact with proteins and cause stability problems such as aggregation. Thus, identifying formulation-compatible preservatives at concentrations that also provide the desired antimicrobial efficacy is a major challenge during drug product development. There is a general consensus that development of high-concentration formulations of mAbs poses serious challenges with respect to the physical and chemical stability of the mAb, such as increased formation of soluble as well as insoluble aggregates which enhance the probability of an immunogenic response as well as give rise to low bioactivity.

Aggregate formation by a polypeptide during storage of a liquid pharmaceutical composition can adversely affect biological activity of that polypeptide, resulting in loss of therapeutic efficacy of the pharmaceutical composition. Furthermore, aggregate formation may cause other problems such as blockage of tubing, membranes, or pumps when the polypeptide-containing pharmaceutical composition is administered using an infusion system.

SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE INVENTION

According to a first aspect of the invention, there is provided a stable, multi-dose liquid composition comprising an antibody and one or more preservatives.

It has been reported that monoclonal antibody formulations containing preservatives, such as phenol, result in soluble and insoluble protein aggregates. Although phenol is used in many peptide and protein-based drugs, there are several reports of interactions between this preservative and protein formulations. It has furthermore been reported that benzyl alcohol causes aggregation of recombinant human interferon-γ (rhIFN-γ), recombinant human granulocyte colony stimulating factor (rhGCSF), recombinant human interleukin-1 receptor antagonist (rhIL-1ra), and monoclonal antibody formulations. It is common knowledge that most protein aggregation is associated with protein conformational denaturation or instability. Benzyl alcohol has been demonstrated to bind to and accelerate aggregation of partially unfolded proteins. In studies with a monoclonal antibody formulation, a concentration of 1% benzyl alcohol resulted in cloudiness and the formation of soluble aggregates. Concentrations of benzyl alcohol greater than 2% in the same monoclonal antibody formulation resulted in precipitation of the protein.

Data is presented herein which surprisingly shows that formulations containing an antibody in combination with a variety of differing preservatives, resulted in formulations with a low content of aggregates during 4 weeks of storage at 40° C. and storage at 5° C. and 40° C. for 3 months.

The term “stable composition” refers to a composition with satisfactory physical stability, satisfactory chemical stability or satisfactory physical and chemical stability.

The term “physical stability” of the protein composition as used herein refers to the tendency of the protein to form biologically inactive and/or insoluble aggregates of the protein as a result of exposure of the protein to thermo-mechanical stresses and/or interaction with interfaces and surfaces that are destabilizing, such as hydrophobic surfaces and interfaces. Physical stability of the aqueous protein compositions is evaluated by means of visual inspection and/or turbidity measurements after exposing the composition filled in suitable containers (e.g. cartridges or vials) It is an inherent quality of highly concentrated formulations of mabs to exhibit opalescence due to Raleigh scattering. Thus, a composition cannot be classified as physically unstable with respect to protein aggregation, when it shows visual turbidity in daylight. However, when there are precipitates or phase separation visible in day light the formulation is classified as physically unstable.

The term “chemical stability” of the protein composition as used herein refers to chemical covalent changes in the protein structure leading to formation of chemical degradation products with potential less biological potency and/or potential increased immunogenic properties compared to the native protein structure. Various chemical degradation products can be formed depending on the type and nature of the native protein and the environment to which the protein is exposed. Elimination of chemical degradation can most probably not be completely avoided and increasing amounts of chemical degradation products is often seen during storage and use of the protein composition is well-known by the person skilled in the art. Most proteins are prone to deamidation, a process in which the side chain amide group in glutaminyl or asparaginyl residues is hydrolysed to form a free carboxylic acid. Other degradation pathways involve formation of high molecular weight transformation products where two or more protein molecules are covalently bound to each other through transamidation and/or disulfide interactions leading to formation of covalently bound dimer, oligomer and polymer degradation products (Stability of Protein Pharmaceuticals, Ahern. T. J. & Manning M. C., Plenum Press, New York 1992).

Oxidation (of for instance methionine residues) can be mentioned as another variant of chemical degradation. The chemical stability of the protein composition can be evaluated by measuring the amount of the chemical degradation products at various time-points after exposure to different environmental conditions (the formation of degradation products can often be accelerated by for instance increasing temperature). The amount of each individual degradation product is often determined by separation of the degradation products depending on molecule size and/or charge using various chromatography techniques (e.g. SEC-HPLC and/or RP-HPLC).

SEC-HPLC is in particular used for quantification of protein aggregates. The samples may for instance be analysed using a TSK G3000 SWXL column, isocratic elution and subsequent UV detection at 214 nm. This method is used to determine monomeric IgG content and % High Molecular Weight Proteins (HMWP) consisting of dimeric species or larger which are separated according to size by the gel resin. The monomeric content and % HMWP are determined relative to the total protein content detected by the method.

Hence, as outlined above, a stable composition refers to a composition with satisfactory physical stability, satisfactory chemical stability or satisfactory physical and chemical stability. A satisfactory stability of a formulation may be measured by the increase of % High Molecular Weight Proteins (Δ% HMWP). A satisfactory stability of a formulation may be one wherein the increase is less than 10% and preferably less than 5% of the protein found as an aggregate (Δ% HMWP) in the formulation over the testing period. In general, a composition must be stable during use and storage (in compliance with recommended use and storage conditions) until the expiration date is reached.

The term “protein”, “polypeptide” and “peptide” as used herein means a compound composed of at least five constituent amino acids connected by peptide bonds. The constituent amino acids may be from the group of the amino acids encoded by the genetic code and they may be natural amino acids which are not encoded by the genetic code, as well as synthetic amino acids. Natural amino acids which are not encoded by the genetic code are e.g. hydroxyproline, y-carboxyglutamate, ornithine, phosphoserine, D-alanine and D-glutamine. Synthetic amino acids comprise amino acids manufactured by chemical synthesis, i.e. D-isomers of the amino acids encoded by the genetic code such as D-alanine and D-leucine, Aib (a-aminoisobutyric acid), Abu (α-aminobutyric acid), Tle (tert-butylglycine), β-alanine, 3-aminomethyl benzoic acid and anthranilic acid.

EXAMPLES Example 1 4 Week Stability Analysis at 40° C. for Anti-IL-20

12 formulations were prepared (see Table 1 below). The formulations were prepared from a stock solution containing ca. 150 mg/ml of the Anti-IL-20 antibody and 10 mM histidine buffer, pH 6.5. This stock solution was prepared by conventional UF/DF/UF. Stock solution of the excipients were prepared and mixed in the correct proportion. The final formulations were filled in 3 ml Penfill® cartridges, type 1 glass. The formulations were stored at 40° C. for 4 weeks and then analysed chemically, pharmaceutically and biophysically. The increase in the formation of protein aggregates (% HMWP) was measured by SEC-HPLC (as described above).

TABLE 1 Composition of tested formulations Anti-IL-20 100 mg/ml Histidine 33 mM Arginine 25 mM NaCl 25 mM Polysorbate 80 0.01 mg/ml Preservative(s) Concentration varied pH 6.5

The results of the stability analysis are shown in Table 2 and demonstrates that all tested formulations resulted in a low content of aggregates following 4 weeks storage at 40° C.

TABLE 2 SEC-HPLC Analysis the increase of % HMWP for Anti-IL-20 formed during 4 weeks study (Δ % HMWP). Storage time (weeks) Δ % HMWP at 40° C.

In particular, it should be noted that the compositions containing 2 preservatives (phenol and m-cresol) generally resulted in lower aggregate formation than the results achieved with the individual preservatives alone. Most surprisingly, it can be seen that the composition containing 5 mg/ml phenol alone resulted in an increase of 2.5% HMWP and the composition containing 3.5 mg/ml m-cresol alone resulted in an increase of 3.1% HMWP, however, a composition containing a combination of these two preservatives at identical concentrations resulted in a lowering of aggregate formation (an increase of 1.2% HMWP). An increase of 1.1% is seen for reference without preservative.

Potency was investigated after 4 weeks storage at 40° C. and the results are shown in Table 3. These results demonstrate that full potency was obtained for all formulations.

In particular, it should be noted that the composition containing 3.5 mg/ml m-cresol resulted in the smallest increase in HMWP. After 3 months storage the increase in HMWP for this formulation is lower compared to reference without preservative.

The results of the stability analysis at 5° C. are shown in Table 6 and demonstrates that all tested formulations resulted in a low content of aggregates following 12 months storage at 5° C.

The robustness of the formulations was also assessed with respect to cycles of freeze-thaw (−80° C. to room temperature) and thermal and mechanical stress (4 hours daily rotation during 2 weeks storage at 37° C.). Data are given in below Table 8, and these indicate that the formulations are robust against physical stress.

At time zero all samples were found to be clear to slightly opalescent without any visible particles using both analytical methods. No difference was observed after the formulations were exposed to the above stress conditions.

Example 3 Results from Modified Preservative Efficacy Test for Anti-IL-20

To analyze the efficacy of different preservatives, a preservative efficacy screening test was performed. The efficacy of the preservative was measured using a modified USP/Ph Eur preservative efficacy test. In the modified test, formulations were tested against Staphylococcus aureus. After inoculation, samples were stored for 6 and 24 hours at room temperature and the total bacterial counts were measured using a colony counter. The log reduction values were calculated as log (initial count/final count).

In the unmodified USP/Ph Eur preservative efficacy tests several bacteria and fungi are tested. The USP and Ph Eur regulatory requirements are listed here below in Table 9. It should be noted that the Ph Eur requirements are more stringent than those of the USP, and that the Ph Eur requirements offer a minimal level that must be achieved (B criteria) and a suggested level that is recommended (A criteria). The preservative efficacy test was modified in this study to reduce the sample requirements and cost per analysis. Staphylococcus aureus was chosen in the modified preservative test because it was the most resistant pathogen for the chosen formulations.

The results of the modified preservative efficacy test show that the formulation with 3 mg/ml phenol complies with criteria B in Ph Eur and formulations with 5-7 mg/ml phenol and 4-6 mg/ml m-cresol demonstrate a complete kill of Staphylococcus aureus after 24 hours. By the performed test the formulations have been demonstrated to be suitable as multi-dose formulations.

The stability of above formulations used in the preservative efficacy screening study with respect to formation of % HMWP is given in below in Table 12. As can be observed, increasing amounts of preservatives leads to increasing amounts of % HMWP, however, several of above formulations are stable and have satisfactory preservative effect.

Example 4 3 Month Stability Analysis at 5° C. and 40° C. for Anti-TFPI

This study was conducted in an analogous manner to that described in Example 2 with the exception that the study was conducted with an Anti-TFPI antibody rather than the Anti-IL-20 antibody. The formulations tested are as described in Table 13.

TABLE 13 Composition of tested formulations Anti-TFPI 100 mg/ml Histidine 33 mM Arginine 25 mM NaCl 25 mM Polysorbate 80 0.01 mg/ml Sucrose To tonicity Preservative(s) Concentration varied pH 6.0

The results of the stability analysis at 40° C. are shown in Table 14 and demonstrates that all tested formulations resulted in a significantly higher content of aggregates following 3 months storage at 40° C.

TABLE 14 SEC-HPLC Analysis of increase of % HMWP for Anti-IL-20 formed during 3 month study at 40° C. (Δ % HMWP). Months of storage at 40° C. Δ % HMWP 0.5 1 3 Reference 0.0 0.9 3.2 Phenol 5 mg/ml 3.3 9.5 17.4 Phenol/m-cresol 1.5/1.8 mg/ml 0.5 2.2 7.6

In particular, it can be seen that 5 mg/ml phenol resulted in a 4 fold increase in aggregate formation when compared with the reference formulation. By contrast, the same concentration of preservative in the Anti-IL-20 containing formulation resulted in only a 2.1 fold increase (see Table 5). However, the results with the combination containing phenol and m-cresol were equivalent to those obtained for Anti-IL-20 (i.e. a 1.9 fold increase in aggregate formation for Anti-TFPI c.f. a 1.8 fold increase for Anti-IL-20; see Table 5).

The results of the stability analysis at 5° C. are shown in Table 15 which demonstrates that all tested formulations resulted in a low content of aggregates following 3 months storage at 5° C.

Visual appearance analysis was performed in light cabinet and architect lamp for all formulations to assess the possibility of formation of particles. At time zero all samples were found to be clear to slightly opalescent without any visible particles using both analytical methods. No difference was observed after the formulations were exposed to the above stress conditions.
